Propane Tanker Trailer Safety

Propane Tanker Trailer Safety

Propane is a flammable gas that is regulated for transport under the Transportation of Dangerous Goods (TDG) Act and Regulations. The movement of any propane tank or cylinder is fully regulated under the TDG Regulations unless an exemption applies.

The use of “Liquefied Petroleum Gas” as the shipping name is intended for mixtures of petroleum gases containing any of the following: BUTANE (UN1011), BUTYLENE (UN1012), ISOBUTYLENE (UN1055), PROPYLENE (UN1077), ISOBUTANE (UN1969), and PROPANE (UN1978). If UN1978, PROPANE, is to be transported on a road vehicle and is identified as LIQUIFIED PETROLEUM GAS on the shipping document, the shipping name PROPANE must be shown, in parentheses, following the words LIQUIFIED PETROLEUM GAS.

All compressed gas cylinders are considered dangerous because they contain gas under pressure. The cylinder’s valve can easily be damaged by falling or striking another object; something that could create a rocket out of an ordinary cylinder. The TDG Regulations [Section 5.4] say only that the small means of containment must be loaded and secured on a means of transport in such a way as to prevent, under normal conditions of transportation, damage to the means of containment or to the means of transport that could lead to an accidental release of the dangerous goods.
